Summary of the invention
The problem that invention will solve
But, in the isolation mounting passing prior art, still room for improvement is existed for following situation: the vibration for wide range of frequencies plays attenuation characteristic.
Make the present invention in view of the foregoing, the object of this invention is to provide a kind of isolation mounting that can play attenuation characteristic for the vibration of wide range of frequencies.
For the scheme of dealing with problems
In order to solve the problem, the present invention proposes following means.
Isolation mounting related to the present invention comprises the first installation component and second installation component of tubular, described first installation component connects with vibration generating unit and the one vibrated in acceptance division, and described second installation component connects with the another one in described vibration generating unit and described vibration acceptance division; Elastomer, described elastomer makes described first installation component and described second installation component connect; Partition member, described partition member is fitted in described first installation component, and described partition member defines main liquid chamber and the first secondary liquid chamber of arranging independent of described main liquid chamber and the second secondary liquid chamber, and described main liquid chamber is using described elastomer as a part for its wall; First barrier film, described first barrier film constitutes a part for the wall of described first secondary liquid chamber; And second barrier film, described second barrier film constitutes a part for the wall of described second secondary liquid chamber, and the deformation resistance of described second barrier film is less than the deformation resistance of described first barrier film.Described partition member is provided with idle hole and shake hole (shakeorifice), described idle hole allows described main liquid chamber and described first secondary liquid chamber to communicate with each other and the input that described idle hole vibrates relative to idling produces resonance, and described shake hole allows described main liquid chamber and described second secondary liquid chamber to communicate with each other and described shake hole produces resonance relative to the input of shake vibration.Adjustment room is configured to across described second barrier film adjacent with described second secondary liquid chamber, and the inside of described adjustment room can relative to standard pressure decompression or pressurization or can open relative to outside inaccessible mode.
In the present invention, shake hole produces resonance relative to shake vibration, and the input that idle hole vibrates relative to idling produces resonance.Therefore, the circulating resistance shaking hole is larger than the circulating resistance of idle hole.
Simultaneously, if vibration be imported into the inside being in adjustment room be embodied as the isolation mounting under the standard state of standard pressure or be in the open standard state of the interior of adjustment room under isolation mounting, then liquid trend flows through idle hole, make the first diaphragm deflection between main liquid chamber and the first secondary liquid chamber, or liquid trends towards flowing through shake hole, makes the second diaphragm deflection between main liquid chamber and the second secondary liquid chamber.Here, because the deformation resistance of the second barrier film is less than the deformation resistance of the first barrier film, makes liquid be difficult to flow between main liquid chamber and the first secondary liquid chamber, and make liquid be easy to flow between main liquid chamber and the second secondary liquid chamber.Therefore, as mentioned above, even if the circulating resistance in shake hole is larger than the circulating resistance of idle hole, liquid also can be made preferentially to circulate but not idle hole in shake hole.
Result, when shaking vibration and being imported into the isolation mounting be under standard state, can make the liquid in main liquid chamber preferentially by the shake hole circulation between main liquid chamber and the second secondary liquid chamber, thus shake vibration can be absorbed and be decayed by the resonance produced in shake hole.
On the other hand, if the inside of the adjustment state reduced pressure relative to standard pressure or pressurize in the inside that isolation mounting is embodied as adjustment room or adjustment room is relative to outside inaccessible adjustment state, compared with the isolation mounting situation be under standard state, the second barrier film can be limited and the deformation resistance of the second barrier film can be improved.Correspondingly, make liquid be difficult to circulate between main liquid chamber and the second secondary liquid chamber, and make liquid be easy to circulate between main liquid chamber and the first secondary liquid chamber.As a result, liquid can be made preferentially to be circulated by idle hole but not shake hole.
Result, when idling vibration is imported into the isolation mounting be under adjustment state, can make the liquid in main liquid chamber preferentially by the idle hole circulation between main liquid chamber and the first secondary liquid chamber, thus idling vibration can be absorbed and be decayed by the resonance produced in idle hole.
According to isolation mounting, by switching between standard state and adjustment state, can absorb respectively and damping flicker vibration and idling vibration, thus attenuation characteristic can be played for the vibration of wide range of frequencies.
In addition, in above-mentioned isolation mounting, partition member can be provided with: locking hole (lock-uporifice), and described locking hole extends from described main liquid chamber to described second secondary liquid chamber and produces resonance relative to the input of locking vibration; Containing room, described containing room allows described locking hole and described second secondary liquid chamber to communicate with each other; And movable body, described movable body is being accommodated in described containing room in the mode be axially shifted of described first installation component, and described movable body can being accommodated in described containing room in the described mode be axially shifted, thus when inputting the vibration of described locking, described locking hole and described second secondary liquid chamber are communicated with each other by described containing room, when inputting described shake vibration, described locking hole is cut-off by being communicated with of described containing room with described second secondary liquid chamber.
In this case, when shaking vibration and being imported into the isolation mounting be under standard state, movable body is shifted in the axial direction, locking hole and the second secondary liquid chamber cut-off by being communicated with of containing room.Therefore, the liquid in main liquid chamber can be made by the shake hole circulation between main liquid chamber and the second secondary liquid chamber, thus shake vibration can be absorbed and be decayed by the resonance produced in shake hole.
Meanwhile, because locking hole produces resonance relative to locking vibration, make the circulating resistance of locking hole all less than the circulating resistance in idle hole and shake hole.Therefore, with idle hole or shake compared with hole, liquid can be made preferentially to circulate at locking hole.
As a result, when locking vibration is transfused to the isolation mounting be under standard state, liquid can be made preferentially by the locking hole circulation between main liquid chamber and the second secondary liquid chamber, thus locking vibration can be inhaled and be decayed by the resonance produced in locking hole.
According to this isolation mounting, in normal conditions, can absorb and damping flicker vibration and locking vibration, attenuation characteristic can be played for the vibration of more wide range of frequencies.
The effect of invention
According to isolation mounting related to the present invention, attenuation characteristic can be played for the vibration of wide range of frequencies.

Here, partition member 17 is provided with idle hole (idleorifice) 31, shake hole 32, locking hole (lock-uporifice) 33, containing room 34 and movable body 35.
Idle hole 31 allows main liquid chamber 14 and the first secondary liquid chamber 15 to communicate with each other.Idle hole 31 is formed at the main component 20 of partition member 17, and this idle hole 31 configures and extends in the axial direction with avoiding axis.The frequency that the resonant frequency of idle hole 31 and idling are vibrated (such as, frequency: 15Hz to 40Hz, amplitude: ± below 0.5mm) is equal, and the input that idle hole 31 vibrates relative to idling produces resonance (liquid column resonance).

Such as, under the state that the movable body when allowing main liquid chamber 14 to be communicated with each other by containing room 34 with the second secondary liquid chamber 16 is separated with the internal surface of containing room 34, movable body 35 alternately can be shifted to axial both sides.In addition, when main liquid chamber 14 and the second secondary liquid chamber 16 by containing room 34 be communicated with cut-off, movable body 35 such as can alternately inaccessible locking hole 33 and intercommunicating pore 36, or can any one party continuously in inaccessible locking hole 33 and intercommunicating pore 36.
In isolation mounting 10, the deformation resistance of the second barrier film 19 is less than the deformation resistance of the first barrier film 18.In addition, such as can be adjusted the deformation resistance of the first barrier film 18 or the second barrier film 19 by the volume-variation amount etc. suitably changing unit load in the flexural rigidity of each component, each component according to the Young's modulus of material, the thickness of each component etc. of each component of formation.
Isolation mounting 10 is liquid sealed-in types, and wherein the liquid such as such as ethylene glycol, water or silicone oil is enclosed isolation mounting 10.The secondary liquid chamber 16 of main liquid chamber the 14, first secondary liquid chamber 15, second in isolation mounting 10, idle hole 31, shake hole 32, locking hole 33, containing room 34 and intercommunicating pore 36 all filling aforesaid liquids.
Then, the effect of isolation mounting 10 will be described.
When isolation mounting 10 is configured between vibration generating unit and vibration acceptance division, the initial load that second installation component 12 is shifted to opposite side relative to the first installation component 11 is applied to isolation mounting 10, main liquid chamber 14 is shunk, thus makes the hydraulic pressure fluctuation of main liquid chamber 14 and raise.Here, in isolation mounting 10, the deformation resistance of the second barrier film 19 is less than the deformation resistance of the first barrier film 18.Thus, the liquid be pushed out from main liquid chamber 14 in this case flows into the second secondary liquid chamber 16, and this second secondary liquid chamber 16 is using the second barrier film 19 as a part for its wall.
In addition, when the above-mentioned control unit of regulating mechanism 25 controls switching valve 27, the adjustment state that the interior pressure of standard state and adjustment room 24 as shown in Figure 2 that the interior pressure of the adjustment room 24 that isolation mounting 10 is switched to as shown in Figure 1 is embodied as standard pressure reduces relative to standard pressure.In the isolation mounting 10 be under adjustment state, along with the inner pressure relief of adjustment room 24, the second barrier film 19 closely contacts with diapire face with the peripheral wall surfaces of adjustment room 24, and adjustment room 24 is disappeared by compressing, and the second secondary liquid chamber 16 is expanded.If the decompression of the inside of adjustment room 24 is removed, then make the second barrier film 19 reduce and be out of shape, and adjust room 24 and revert to standard pressure.
Such as, when isolation mounting 10 is applied to Motor Vehicle, above-mentioned control unit can control switching valve 27 according to the revolution or the speed of a motor vehicle being used as the motor vibrating generating unit.In addition, in this case, when Motor Vehicle is in travelling state, control unit makes connecting tube 26 be connected with barometric pressure solenoid 30 by switching valve 27, and makes the interior pressure of adjustment room 24 be implemented as atmospheric pressure as standard pressure.In addition, when Motor Vehicle is in idling mode, control unit makes connecting tube 26 be connected with negative tube 29 by switching valve 27, and the interior pressure of adjustment room 24 is reduced.In addition, when intake manifold is used as sourceof negative pressure 28, the inside air-intake negative-pressure (intakenegativepressure) that intake manifold can be utilized to produce of adjustment room 24 and reducing pressure.
If vibration is imported into the isolation mounting 10 being in standard state shown in Fig. 1 in the axial direction, then both installation components 11 and 12 are relative to each other shifted in the axial direction, and elastomer 13 is flexibly out of shape, and the fluctuation of the hydraulic pressure of main liquid chamber 14.Then, liquid trends towards flowing through idle hole 31, and the first barrier film 18 between main liquid chamber 14 and the first secondary liquid chamber 15 is out of shape, or liquid trends towards flowing through shake hole 32 or locking hole 33, and the second barrier film 19 between main liquid chamber 14 and the second secondary liquid chamber 16 is out of shape.
Here, in isolation mounting 10 as above, the deformation resistance of the second barrier film 19 is less than the deformation resistance of the first barrier film 18.Thus, make liquid be difficult to flow between main liquid chamber 14 and the first secondary liquid chamber 15, and liquid is easy to flow between main liquid chamber 14 and the second secondary liquid chamber 16.Therefore, in the present embodiment, even if the circulating resistance in shake hole 32 is larger than the circulating resistance of idle hole 31, liquid also can be made preferentially to be circulated but not idle hole 31 by shake hole 32.
As a result, when shaking vibration and being input to isolation mounting 10, the liquid in main liquid chamber 14 trends towards preferentially flowing through the shake hole 32 between main liquid chamber 14 and the second secondary liquid chamber 16 or locking hole 33.In this case, movable body 35 is shifted in the axial direction, and locking hole 33 is cut-off by being communicated with of containing room 34 with the second secondary liquid chamber 16.Therefore, the liquid in main liquid chamber 14 can be made not circulated by shake hole 32 by the locking hole 33 between main liquid chamber 14 and the second secondary liquid chamber 16, thus can by shaking the resonance absorption and damping flicker vibration that produce in hole 32.
In addition, in isolation mounting 10, the circulating resistance of locking hole 33 is less than the circulating resistance in shake hole 32.Therefore, when locking vibration is input to the isolation mounting 10 be under standard state, liquid can be made preferentially to be circulated by the locking hole 33 between main liquid chamber 14 and the second secondary liquid chamber 16.As a result, can by the resonance absorption that produces in locking hole 33 and the vibration of decay locking, such as can to absorb by suppressing the increase of the dynamic spring constant of isolation mounting 10 and locking of decay vibrates.
On the other hand, compared with the situation being in standard state with isolation mounting 10, as shown in Figure 2, if isolation mounting 10 achieves the adjustment state that reduces pressure relative to standard pressure of inside of adjustment room 24, then can limit the second barrier film 19 and the deformation resistance of the second barrier film 19 can be improved.Correspondingly, make liquid be difficult to circulate between main liquid chamber 14 and the second secondary liquid chamber 16, and liquid can be made to be easy to circulate between main liquid chamber 14 and the first secondary liquid chamber 15.As a result, liquid can be made preferentially to be circulated by idle hole 31 but not circulated by shake hole 32 or locking hole 33.
As a result, when idling vibration is input to the isolation mounting 10 being in adjustment state, the liquid in main liquid chamber 14 can be made preferentially to be circulated by the idle hole 31 between main liquid chamber 14 and the first secondary liquid chamber 15.As a result, can by the resonance absorption that produces in idle hole 31 and the vibration of decay idling, such as can to absorb by suppressing the increase of the dynamic spring constant of isolation mounting 10 and the idling that decay is vibrated.
As mentioned above, according to the isolation mounting 10 relevant to present embodiment, by switching between standard state and adjustment state, can absorb respectively and damping flicker vibration and idling vibration, thus attenuation characteristic can be played for the vibration of wide range of frequencies.
In addition, in normal conditions, shake vibration and locking vibration can be absorbed, can for the vibration performance attenuation characteristic of more wide range of frequencies.
Technical scope of the present invention is not limited to above-mentioned mode of execution, and is not deviating from purport situation of the present invention and can carry out various modification.
In the above-described embodiment, can reduce pressure relative to standard pressure in the inside adjusting room 24.But, the present invention is not limited thereto.
Such as, in the first modified example of the present invention, the inside of adjustment room can be pressurized relative to standard pressure, and the inside that the adjustment state of isolation mounting can be implemented as adjustment room is pressurized and limit the state of the second barrier film relative to standard pressure.In this case, such as, above-mentioned sourceof negative pressure can be replaced and adopt pressure source etc.
In addition, such as, in the second modified example of the present invention, the inside of adjustment room can be opened by the mode of obturation relative to outside, the standard state of isolation mounting can be implemented as the open state of the interior of adjustment room, and the adjustment state of isolation mounting can be implemented as adjustment room inside relative to outside by the state of obturation.In this case, in the isolation mounting being in adjustment state, the second barrier film can be limited by utilizing the indoor pressure of adjustment as back pressure.In addition, in such configuration, replace above-mentioned switching valve, can adopt and make the open and close valve that the inside of adjustment room is open relative to the outside of isolation mounting or close.In addition, replace switching valve and connecting tube, the switching mechanism directly opening and closing attachment hole can be adopted.
In addition, locking hole 33, containing room 34, movable body 35 and intercommunicating pore 36 can not be set.
In addition, well-known composed component can be utilized when not deviating from design of the present invention suitably to replace composed component in above-mentioned mode of execution, and can suitably combine above-mentioned mode of execution.
